To all whom 'it may concern: t

Be it known that I, SAMUEL S. GIORDANO, a subject of the King of Italy, residing at Rockford, in the county of vWinnebago and State of Illinois, have invented certain new and useful Improvements in Moving-Picture Machines, of which the following is a speci fication.

The object of this invention is to construct a moving picture machine which will eliminate, to a considerable extent, the vibration of the pictures when projected upon a screen.

In the accompanying drawings, Figure 1 is a vertical section on dotted line d d Fig. 2. Fig. 2 is a side elevation in which portions are broken away. Fig.'3 is a sec-v tion on dotted line b b FigQl. Fig. 4 is a top view. Fig. 5 is a section on dotted line c c Fig. 1. Fig. 6 is a section on dotted line a a Fig. l. Fig. 7 is a partial face re re sentation. Fig. 8 is a section on dotted ine c c Fig. 1. Fig. 9 is a face represent-ation of the plates 26 and 27.

The main frame comprises the side plates 1 held suitably separated by the cross bars 2, and the frame is supported upon the stand The side plates support a mainshaft 4 which is rotated, in this instance, by the crank* 5. This shaft 4 has a spur gear 6 ixedly connected to it. A shaft 7 is Supported by the side plates 1, and has a spurpinion 8 fiXedly connectedl to it and meshes with the spur gear '6. A spurgear 9 has' a fixed connection with thel vshaft 7, and meshes with a spur pinion 10 secured to the shaft 11, supported by the side plate 1. A rod 1.2 is xedly supported by the side plates 1 and has two toothed drums 13 and 13 loosely mounted thereon and held against bodily lengthwise movement on the rod 12 by the collars- 14. To thetoothed drums and integral therewith are formed star wheels 15 and 15 provided 1 with radial slots 16 and 16 respectively. To the shaft 7 are ixedly connected two' out away cams 17 and 17 and to each cam is secured a yoke 18 and 18 respectively having a cross bar 19 and 19 respectively at its outer end.v As the shaft 4 is rotated by the crank 5, the cross bars 19 and 19 will enter rthe slots 1.6 and 16 of the star wheels thereby imparting an intermittent rotary movement to the star wheels, and to the toothed drums 13 and 13. The yokes 18 and 18 are set opposite one another so that one toothed drum remains stationary during the movement of the other drum, and the cams 17 and 17 being received in the curved or hollow portions of the star wheels will prevent the movement of the star wheels until moved by the cross bars 19 and 19 of the yokes 18 and 13.

Adjacent to the rod 12, is a rod 2() upon which are located two grooved rollers 21 and '21 which are in line with the toothed drums 13 and 13. The teeth of t-he drums are received in the grooves of the rollers. Tothe upper portion of the side bars 1 of the frame are secured fbrackets 22 which support a rod 23, and it supports two spools 24 and 24 which turn thereon. To the upper portion of the side bars 1 of the frame is secured a plate 25 having an upturned end 26. This upturned end 26 supports a plate 27 which is spaced therefrom by the blocks 28. Each spool 24 and 24 has a tape film 29 and 29 wound upon it, and the films pass between the toothed drums 13 and 13, and the grooved rollers 21 and 21, the teeth of the drums entering perforations` in the films, and as the toothed drums are intermittently rotated, the films will be intermittently moved vertically between the plates 26 and 27, and downwardly. The plates 26 and 27`are formed with openings 30 and 31 respectively. Theplate 25 supports two olojective lenses 32 and 32 which are adjusted on the bolt 33 through the seat, and bolt 34 so as to focus them at a commonpoint.

The shaft 11 has a cut. away cam 35 secured to it, and to this cam is secured a yoke 36 supporting a rod 37 at its free-end. A shaft 38 is supported in the side plates 1 of the frame, and to it is secured a star wheel 39 provided with radial slots 40. The rod 37 of the yoke 36 enters the radial slots 40 of the star wheel 39, thereby imparting an intermittent rotary movement to the shaft 38.

To the shaft 38 are secured two cams 41 and 41.

. A rod 42 is supported by the side plates 1, and to this rod is iixedly connected a shutter, comprising the end plate 43 having two openings 44 and 44, and side bars 45 and 45 which are fixedly connected to the rod 42. The end of the side bar 45 has a depending end 46 which is located against the Outerv face of one of the cams 41 as shown at Fig.

6, and the other side bar 45 of this shutter shown at Fig. 3. The two cams 4l and 41 are set with their larger portions opposite, and the two depending ends 4G and 4t which are moved by these cams will impart a positive oscillatory movement to the end 43 of the shutter. The two openings 44 and 44 in the shutter are located one above the other, while the two openings 30 and 31 in the plates 26 and 27 respectively are located in the same horizontal plane.

From the frame depend two arlus 48 to which is pivoted a rod 49. lo this rod 49 is fixedly connected a bar 50. The upper end of this bar 50 is formed with a fork 5l which receives anl eccentric 52 fixedly connected to the shaft 7. The lower end of this bar 50 has a dog 53 pivotally connected to it, and a spring 54 exerts its infiuence upon the dog to hold it yieldingly in an upward direction. From the frame depend two projections 55 which support a rod 56 in a fixed manner, and on this rod are mounted two yokes 57 and 57. in a pivotal manner. Each yoke supports a rod 58 and 58 respectively', and each rod supports a spool 59 and 59 respectively. To each spool is fixedly connected a ratchet wheel 60 and 60 with which the dog 53 engages. From the yokes 57 and '57 rise projections 6l and 6l and each projection has a dog 62 and 62 `pivoted to it and overlying the ratchet wheels 60 and 60 re spectively. The films 29 and 29 are wound upon these spools 59 and 59 respectively.

Duringwthe rotation of the shaft 7, the eccentric 52 will rotate with it, whichwill oscillate the bar 50, and cause the dog 53 to engage the teeth of the ratchet wheels G0 and G0 thereby partially rotating the spools 59 one filmv remains at rest during the move' ment of the other film. The openings in the shutter will alternately expose the two films, and when one film 1s covered, that film is being moved to present a new section of it.

By this arrangement two films are employed to present a continuous picture which is projected upon a screen by the two lenses 32 and 32 which are focused to a common point on the screen.

By the employment of two films, each containing one-half of the pictures of a given scene and exposing the pictures alternately of the films, the change from one film to the other is not apparent, as one picture is always on the screen, thereby the vibration of the pictures ou the screen is practically obviated.

claim as my invention.

l. In a moving picture machine, means for alternately actuating two coacting films, devices for projecting pictures from the films so actuated, a single pivotally mounted shutter that operates across both projecting devices and is provided with openings therethrough, said openings being disposed in a sequence to successively register with the projecting devices, and means for swinging the shutter back and forth on its'pivot axis to alternately expose the pictures of the different films. Y

2. In a moving picture machine, the combination with means for alternately actuating two coacting films, of lenses located side by side for projecting pictures from the lms so actuated, an oscillatory shutter operating across said lenses and having openings disposed in a sequence to successively register with the lenses for effecting an alternate projection of the pictures, said shutter including a pair of swinging arms, a rotary shaft, and cams carried by the shaft and alternately operating on the arms to swing the same in opposite directions.

In testimony whereof Ihave hereunto set my hand in presence of two subscribing witnesses.
